CAN-FILLING MACHINE.

Application filed June 11,

My invention relates to can filling. machines and more particularly tomechanism for automatically shutting off the feed when there is no canin position to be filled. The objects of my invention are to providesimple and eflicient mechanism whereby the feed openings are closedexcept when temporarily cleared by mechanism actuated by a can in itspassage to the filling point, and to provide common means for closingand clearing the openings for passage of both granular material andliquid.

These objects, and other advantageous ends which will be describedhereinafter, 1 attain in the following manner, reference being had tothe accompanying drawings in which Figure 1 is a side elevation of partof a can filling machine embodying my invention,

Figure 2 a diagrammatic sectional view, partly broken away, on line 2.2of Figure 1, showing the cut-off in operative positlon,

Figure 3 alike view showing the cut-off in inoperative position,

Figure 4 a sectional view on line 4.-.-4 of Figure 1, and

Figure 5 a fragmentary vertical section showing parts of the granularand brine feeding mechanism.

Referring to the drawings, 1 indicates the feed hopper of acan fillingmachine, 2 the distributing wheel for granular material, 3 the measuringcups for the granular material, 4 the bed plate upon which the measuringwheel rotates which is provided with an opening 5 for passage ofgranular material and an opening 6 for passage of liquid, 7 the bedplate upon which a liquid measuring wheel 8 rotates, which is providedwith an opening 7 adapted to register with opening 6, 9 a liquid cup, 10a funnel wheel provided with funnels 11 for directing granular materialand pockets 12 fordirecting liquid to cans 13, 14 a star wheel, 15 avertical shaft by which rotation is imparted to the granular measuringwheel, the funnel wheel and the star wheel and 16 guides for directingcans into the machine. The parts above enumerated constitute no part ofthis invention and the illustration is conventional only.

A rod 17 is rotatably mounted in bearings 1924. Serial N0. 719,268.

upon fixed parts of the frame and has a cut-01f plate 18 fixed to itsupper end. The cutoff plate is preferablysubstantially heart shaped andis adapted to be swung over and to close an opening 5 and opening 6thereby cutting off the feed of both granular material and liquid. Acurved arm 19, hereinafter called the actuating arm, has one endpivotally connected at 20 to a fixed part of the frame, adjacent thepoint of entry of the cans, and normally extends into the path of travelof the cans after they come under the domination of the star wheel. A.crank arm 21 is fixed to rod 17 and pivotally con nected to a link 22which is pivotally connected to actuating arm 19 at 23. A coiled spring24: is connected to crank arm 21 and to a fixed part of the frame andnormally holds actuating arm 19 in the path of travel of the cans.Gut-off plate 18 is so positioned upon rod 17 that, when arm 19 is heldin the path of travel of the cans, the cut-oil plate will be heldin theposition indicated in Figure 2 and will close an opening 5. and opening6 thereby shutting oil the feed of both granular material and liquid.When a can is fed to the machine and comes under the domination of thestar wheel, it contacts with actuating arm 19 and forces it outwardlyagainst the tension of spring 24 and also imparts contra-clockwisemovement to rod 17 and retracts cut-off plate 18 to the positionindicated in Figure 3 thereby clearing an opening 5 for passage ofgranular material and opening 6 for passage of liquid.

As a can passes beyond the openings and beyond actuating arm 19, thespring automatically restores the cut-off plate to its closed positionand the openings remain closed until the succeeding can retracts thecut-off plate.

If for any reason there is -a failure in can feed the cut-off plate isheld in its operative position with the openings closed until 7 Gil I amat liberty to make such changes and alterations as fairly come withinthe scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is 1. In a can filling machine, a distributingwheel having a plurality of measuring cups for granular material; adistributing Wheel for liquid material; a bed plate for the ranulardistributing wheel having openings Ior discharge of granular and liquidmaterial; a cutoff plate normally closing both openings, and meansactuated by the cans for clearing the openings.

2. In a can filling machine, a bed plate; a measuring wheel for granularmaterial mounted thereon; a second bed plate; a liquid measuring wheelmounted thereon, the

first named bed plate having an opening for discharge of granularmaterial, and an open ing for discharge of liquid, and the second bedplate having an opening for discharge of liquid; a cut-off platenormally closing an opening in the first named bed plate for dischargeof granular material and the opening for discharge of liquid, and meansactuated by the cans for clearing the openings.

3. In a can filling machine, a bed plate; a measuring wheel for granularmaterial mounted thereon; a second bed plate; a liquid measuring Wheelmounted thereon, the first named bed plate having an opening fordischarge of granular material, and an open for discharge of liquid, andthe second bed plate having an opening for discharge of liquid; acut-off plate normally closing an opening in the first named bed platefor discharge of granular material and the opening for discharge ofliquid, an actuating arm extending into the pathway of the cans;connections between the actuating arm and the cut-off plate wherebymovement of the arm will actuate the cutoff plate to clear the openings,and means normally holding the cut-oif plate in closed position.

4. In a can filling machine, a distributing wheel; a bed plate suiiporting the distributing wheel and having feed openings; means forcausing cans to travel through the machine; a pivoted actuating armextending in the pathway of the cans; a'rotatably mounted rod; a cut-offplate carried thereby normally closing the feed openings; a crank armsecured to the rod; a link pivotally secured to the crank arm and theactuating arm, and means for yieldingly holding the actuating arm in thepath or" travel of the cans and the cut-oil plate in closing position.

5. In a can filling machine, a distributing wheel; a bed platesupporting the distributing wheel and having feed openings; means forcausing cans to travel through the machine; a pivoted actuating armextending in the pathway of the cans; a rotatably mounted rod; a cut-offplate carried thereby normally closing the feed openings; a crank armsecured to the rod; a link pivotally secured to the crank arm and theactuating arm, and a spring connecting the crank arm with a fixed partof the machine normally holding the pivoted arm in the path I of travelof the cans and the cut-0E plate in closing position. I

In testimony whereof I have signed my name to this specification.

CHARLES H. AYARS.
